Alternator pulley removal?

[Josie'sLandCruiser]

Hi All:

Swapping a high-output Delco alternator into my FJ40. Went to remove the pulley from the Toyota alternator and I cannot get it off!

I used an impact gun to remove the "big nut" but the pulley will not come off, despite efforts to pry it off.

Any suggestions?

TIA!

A second pair of hands. Seriously. Have someone else hold the pulley while you tap the shaft of the alternator with a brass drift [to protect the threads]

And put something soft under the alternator [assuming you're holding it vertically to let gravity be your friend], because once the rust releases, it moves FAST!

This is good advice. -----All I would add is to soak it with penetrating oil for at least 24 hours before attempting to remove it.

Heat, lube and a small hammer. Sometimes a puller in the worst cases, but used very lightly as a set of second hands. Usually its the keyed 1/2 round piece that doesnt want to slide loose.

Hi All:

Thanks for the responses, guys! I assumed that penetrating oil and heat would probably be needed at some point!

Sometimes driving (tapping) the pulley in helps to loosen it up after applying the oil.

Can you get a power steering pulley puller on it?

Hi All:

Again, thanks for all the suggestions.

I was surprised at how easily the pulley came off once I applied some Kroil then tapped the shaft with a punch and brass hammer.
